Application filed November ing at Maplewood, in the county of Essex,

a State of New Jersey, have invented certain new and useful Improvements in Distributing Apparatus, of which the following is a full, clear, concise, and exact description. 'This invention relates to distributing apparatus, and particularly'to an improved type of apparatus for distributing current impulses of desired length in proper sequential order. The. invention is particularly applicable for use in printing telegraph systems of the multiplex synchronous type, although obviously not limited to such use.

An object of this invention is the provision of means whereby the distributing apparatus at one station may be brought into the desired phase relation or into synchronism with a similar distributing apparatus at a remote or distant station, in a reliable and efiicacious manner.

F or the accomplishment of the above ob-' ject, the invention contemplates the provisionof a distributor fac'e provided with a plurality of rings, some of which are segmented and others continuous, and adapted to be interconnected by conducting brushes The distributor arms are motor driven and are adapted to be rotated. normally at a uniform, predetermined speed, with means provided whereby the'speed of the distributor brushes may be altered momentarily or the phase relation of a plurality of distributor arms changed while they are rotating. The preferred embodiment illustrated in the accompanying drawing comprises a plurality of distributor faces, preferably arranged in separate parallel planes, each distributor face provided with separate and independent brushes. arms may be orientated while they are rotatin and independently of one another.

he invention is'herein illustrated as applied to a multiplex telegraph system, but it is to be understood that it is equally suitable for other signaling systems wherein it is desired to distribute current impulses of definite length in a predetermined or sequential order.

The above and other features of this invention will be fully set forth in the following description and claims and will be more The distributor brush JDI$TBIBUTIN APPARATUS.

readily understood by reference to the accompanying drawings, wherein Fig. 1 is-a side elevation of acurrent impulse distributing apparatus with a part thereof shown in. cross section; Fig. 2 is a View on line 2, 2 Fig. 1, looking to the left; and Fig. 8 is a View on right.

Referring to Fig. 1, the power shaft 10 is driven by a motor 11 of any wellknown construction. Concentric with the power shaft 10 is a. plurality of current impulse-distributing faces which, in a multiplex telegraph system, may be considered correcting, receiving and sending faces, marked C, R and S, respectively.v Eacli face is provided with one or more pairs of rings, as illustrated in Fig. 2, one ring of each pair' beingcontinuous and the other segmented. Each pair of' rings is provided with a set of distributor brushes for the purpose of connecting the segments of the segmented ring with the continuous ring. The brushes are carried by brush arms 12, secured-to a sleeve or collar 13, one end of which is formed into a bevel gear 14.

The bevel gear 14 and collar 13 are loosely mounted on the shaft 10 by means of bearings, as indicated at 15. Associated with each gear lis a second bevel gear 16, which is .keyed or rigidly secured to the driving closing the frame or supporting portion'22 of the distributor head. The center portion of the disc 21 is cut away and is held'in frictional engagement with the distributor head frame 22 by means of a circular plate 23. The frictional engagement between the frame 22, circular plate 23 and disc 21 may line 8, 3 Fig. 1, looking to the be varied or adjusted by means of the screws 24 and springs 25 carried thereby.

It will be seen that when the driving shaft 10 is rotating, the distributor brush arms 12 will revolve at the same R P. M. as that of the driving shaft; but if, for any reason, synchronism is lost between a distributor at one station and a corresponding distributor at a remote station, the speed of the distributor arm at either station may readily be changed, or the desired phase angle between the distributor brush arms may be secured easily and quickly by rotating the disc. 21 to which the gear 17 is secured. The disc 21 may be rotated by hand either clockwise or counter-clockwise, de-- pending upon whether the distributor arm' at that particular station is ahead or behind the corresponding distributor arm at the remote station. In other words, the disc 21 may be turned in whichever direction necessary in order to restore synchronism the most expeditiously. It will be noted that the disc 21, and likewise its corresponding distributor brush. arm, may be rotated throughlany number of degrees required.

At the top of each distributor head and adjacent the overturned portion of the corresponding disc 21, is a graduated scale 26 to indicate the number of degrees or extent of orientation of the corresponding disc.

On the driving motor 11, is mounted a fly-wheel 30, which may be of any desired construction, for

, example, such as'disclosed in Patent 1,271,-

reason, any one of the receivmg stations 362 issued to M. Rainey on J uly2, 1918, .for damping out speed fluctuations.

This type of distributing apparatus is.

well suited for various kinds of service where it is necessary that the receiving and sending distributors be kept in synchronism, and is particularly well suited for service on lines where there are a numberv of receiving stations, receiving from a lesser should get out of synchronism with the sending station, the receiving operator at that station may regain synchronism quick;

ly and efiiciently by simply rotating or orientating the-disc 21 of the receiving distributor until'the signals are received in their proper place. This condition may'be indicated by a recording instrument, such, as a printer or an indicating means, such as disclosed in Patent No. 1,388,507, issued August 23, 1921, may be used.
